Thread: Bitmap index
Hi, on other RDBMS (Oracle,etc...),there is an index called bitmap index that greatly improve performance compared to btree index for boolean value (such as for a sex value,it's either M or F),i would like to know if such index will be implemented inside PostgreSQL. Best regards, PEJAC Pascal
